How do you explain a central idea from an article? How do you find the "key points" that help develop a central idea in an article? I'm confused.

Main ideas are often found at the beginning of paragraphs. The first sentence often explains the subject being discussed in the passage. Main ideas are also found in the concluding sentences of a paragraph. The central idea of a passage is the message that the author is trying to get across to the reader. The central idea is not the topic. A central idea is stated in a sentence, not just one to two words. Central idea most commonly refers to informational texts.

Explanation:

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."

it is grammatically incorrect and is illegible to me and i can not answer it.
